When mounting on one part, first, the cylindrical cover 23 is put down on the support 11 on which the beam 12 is mounted, and is lowered.
The bottom 21 is brought into contact with the back side of the beam 12. In this case, since the bottom 21 has the same cross-sectional shape as the beam 12, the bottom 21 is stably engaged with the back side of the beam 12. Then, the protrusion 22a on the inner surface of the cylindrical cover 23 is
Is fixed to the mounting arm 25b portion of the cover mounting bracket 25 mounted on the base member with a pin 26. In this case, when the pin 26 is pushed into the hole 22b on the cylindrical cover 23 side from the bolt insertion hole 25c of the cover mounting bracket 25, the scalable locking projection 26a of the pin 26 is engaged with the hole 22b to prevent the pin 26 from coming off. Thus, the cylindrical cover 23 is attached to the column 11 by the pin 26. Next, the locking projection 24 ′ a of the pin 24 a of the upper cover 24 is inserted into the hole 23 of the upper surface 23 a of the cylindrical cover 23.
b, the upper cover 24 is attached to the upper surface of the cylindrical cover 23. As described above, the cylindrical cover 23 and the top cover 24 are attached without using bolts.
And the one-push operation of the plastic fastener type fixing structure 28, the workability is extremely good. In addition, as shown in FIG. 3, the upper edge of the beam 12 is substantially continuous with the upper cover 24 and is substantially not an edge but a part of a surface, so that it is safe for humans to touch. .
